Problems with GTK+ .99.8 and Imlib 1.1

[Derek Simkowiak <dereks animal blarg net>]

    Hello,
	First, a quick note before I forget: doing a "make install" with
GTK+ .99.8 did not copy the file glibconfig.h into /usr/local/include/, I
had to do it myself.  I just thought that was weird.

	Anyhow, on to the real problem(s): I am trying to learn GTK+ and
Imlib, so I wrote the attached imageviewer program (it's crappy, but it's
only meant for me as a learning tool, and not for general use).  I can
get it to compile, but I have the following problem:

	Imlib loads the image just fine, but about 50% of the time that 
I run the program it displays a blank, grey window instead of the JPG (or
GIF, or whatever) I loaded.  It seems almost random in when it works and
when it doesn't.

	This is probably some sort of buffer problem (I feel like a newbie
trying to figure out getc() ) but I'd really like to understand what's
going on.  

	The second issue may be a bug in .99.8, because it works just fine
when compiled using .99.5.  Clicking the "close" button from my window
manager no longer exits the program, I have to kill it.  It worked just
fine in .99.5.  See the code below for details (I think I'm catching all
the right signals...).

	Anyhow, I think GNOME (with GTK) is the greatest thing since
sliced bread, and I really want to understand what I'm doing wrong.
Please take a minute to compile this program, reproduce the errors, and
look at the code (because there might be a problem with GTK or Imlib,
although it's probably just a crappy programming job on my part).

Thank You,
Derek Simkowiak
